Bedrock NBT Editor

Bedrock NBT Editor is a free browser tool for editing Minecraft Bedrock Edition and Java Edition NBT files. It accepts files such as level.dat, playerdata, .nbt, .mcstructure, .schem, and .schematic, and automatically detects byte order, headers, and compression across five NBT encodings. Users can search tags, add or remove them, edit values, and download the result. The editor can also export the edited tree as SNBT text and convert between Bedrock files and Java big-endian gzip format. For large files, typed arrays and lazy tree rendering show 200 entries at a time; BigInt preserves 64-bit TAG_Long values such as world seeds and UUID halves. Files are read and parsed locally, with no upload endpoint, and the editor can keep working offline after the page loads. Android users can select a world file through a file manager; iOS users must first put it in the Files app. The MIT-licensed open-source editor lists compatibility with Java and Bedrock server software, including Paper, Fabric, Forge, PocketMine-MP, Nukkit, and Bedrock Dedicated Server. The maker says it is not affiliated with Mojang Studios or Microsoft.

Bedrock NBT Editor supports a broad set of file types and editing actions, with local parsing and offline use after loading. Its mobile file workflow differs by platform: Android can choose from a file manager, while iOS requires files to be placed in Files first.

Bedrock NBT Editor suits Minecraft players and server users who need to inspect or change NBT files in a browser. It also fits users who want local file handling or offline editing after the page loads.

Overview

Bedrock NBT Editor is a browser-based editor and converter for Minecraft Bedrock and Java Edition NBT files. It is best suited to players and server operators who need to inspect or change structured world data. Its breadth of formats and local processing make it a practical general-purpose option, though mobile file handling varies by platform.

Key features

It opens world and player data including level.dat, .dat, .nbt, .mcstructure, .schem, .schematic, extracted chunk payloads, and packet dumps. Automatic detection of byte order, headers, and compression across five NBT encodings keeps routine work moving without manual format selection. That range suits people working across different kinds of Minecraft data, but the editor remains focused on NBT rather than full world-map editing.

Tag search, adding and removing tags, value editing, and download cover the core inspection and modification workflow. SNBT export is useful when a readable text representation is preferable. The editor can also read Bedrock files and write Java big-endian gzip format, or convert in the reverse direction, making it a strong fit for transferring NBT data between editions.

Large files receive some specific attention: typed arrays and lazy tree rendering display 200 entries at a time. TAG_Long values use BigInt, preserving 64-bit values such as world seeds and UUID halves. These choices help avoid sluggish rendering and value loss when handling data with many entries or long numeric fields.

The parser and writer are exposed as window.NBT for browser-console or userscript use, extending the tool's appeal to technically inclined users who want to script NBT operations. It is open source under the MIT license. The maker says it is not affiliated with Mojang Studios or Microsoft.

Pricing

The Free plan costs nothing. It includes the editor with no paid tier, sign-up, or upload quota, so there is no seat or usage allowance to weigh against a paid upgrade. There is no free trial because the product is free outright. This is a straightforward choice for occasional edits and regular use alike; the trade-off is simply that the product is an NBT editor, not a broader paid world-editing suite.

Platforms

Bedrock NBT Editor runs on Android, iOS, and the web. Files are read and parsed locally in the browser, and the page states that it has no upload endpoint; after the page loads, it continues working if the device goes offline. That combination suits users who want to keep world files on their device and may work without a reliable connection.

The mobile workflow is less direct on iOS: files need to be placed in the Files app before editing. Android users can choose a world file from a file manager. Anyone who frequently edits files stored elsewhere on an iPhone or iPad should account for that extra step.

Who it's for

This is a good fit for Minecraft players who need to inspect or adjust NBT values, server operators working with supported Java and Bedrock software, and users moving data between the two editions. Its local parsing, offline operation after loading, broad input support, and scriptable engine make it useful for both straightforward edits and more technical workflows.

Choose a different kind of editor if the main task is visual world-map editing or broader save management. Bedrock NBT Editor's value is in reading and changing NBT structures, not replacing a dedicated world editor.

Pros and cons

• Broad format and encoding support: it accepts common world files as well as chunk payloads and packet dumps, and detects five NBT encodings automatically.
• Useful cross-edition conversion: it reads Bedrock files and writes Java big-endian gzip, with conversion also available in reverse.
• Local and offline-capable: files stay in browser-side processing, and editing can continue after the page loads without a network connection.
• Careful handling of large and long values: 200-at-a-time rendering and BigInt support address two common sources of friction in larger or sensitive NBT files.
• iOS adds a file-preparation step: users must first put files in Files, which makes the workflow less direct than Android's file-manager selection.
• Focused scope: it edits NBT data but does not present itself as a full visual world editor.

Alternatives

Minecraft World Editors is a useful directory for comparing tools aimed at a broader world-editing workflow.

Blocktopograph is worth considering if Android or Windows support is the priority. Nibnya is another free Android option, and its project is licensed under AGPL 3.0.

For Minecraft Java 26.3 users who need a Windows editor with an API, LiveNBTEditor is a free MIT-licensed option. Developers using Node.js 12.0.0 or higher and looking for an API or Linux workflow can consider mc-nbt.

Super-basic Minecraft Bedrock NBT Editor is a free Windows option for editing level.dat settings and raw NBT; it does not edit the save's db directory. Universal Minecraft Tool has a free Windows tier for NBT editing and world settings, while its $5 a year plan is billed $60 billed annually and unlocks full access to all apps.

Bedrock Toolchest is a free Linux and Windows alternative with no paywalls, subscriptions, or account requirement. BedrockMap is a free open-source Windows 10 map editor for Bedrock worlds from versions 1.2 through 1.21.

Verdict

Choose Bedrock NBT Editor if you need a free, local browser tool for searching, changing, and converting Minecraft NBT across Bedrock and Java formats. Its file coverage and offline-capable workflow are compelling strengths; iOS users should expect to stage files in Files first, and anyone seeking full visual world editing should look elsewhere.
